Cheetah 15K.3 SCSI Product Manual, Rev. G 49

Table 7 lists the Standard Inquiry command data that the drive should return to the initiator per the format given

in the

SCSI Interface Product Manual,

part number 75789509, Inquiry command section.

[]

03 means SCSI-3 (Ultra160) implemented.

Note. Seagate has chosen to set this bit to 03, SCSI-3 (Ultra160) implemented, rather than 04, SCSI-4

(Ultra320) implemented, due to compatibility issues with some host bus adapters. This setting will not

affect the Ultra320 functionality of the drive.

[]

The drive can be changed between these two configurations:

02 means response data in SCSI-2/SCSI-3 format.

12 means the drive uses the hierarchical addressing mode to assign LUNs to logical units (default is 12).

R# Four ASCII digits representing the last four digits of the product Firmware Release number. This informa-

tion is also given in the Vital Product Data page C0h, together with servo RAM and ROM release num-

bers.

S# Eight ASCII digits representing the eight digits of the product serial number.

9.3.1 Inquiry Vital Product data

Instead of the standard Inquiry data shown in Table 7, the initiator can request several Vital Product Data

pages by setting the Inquiry command EVPD bit to one. The

SCSI Interface Product Manual

lists the Vital

Product Data pages and describes their formats. A separate Inquiry command must be sent to the drive for

each Vital Product Data page the initiator wants the drive to send back.
